Does anyone know what the S setting is for? It almost seems like it breathes for you. I have spent the last hour going through every setting and combination trying to beat the jerky breathing thing. Thanks!

What machine do you have? It should say something near the power button.

S mode is probably describing S mode bilevel CPAP, where the machine gives you one pressure when you're inhaling and a lower pressure when you exhale. S mode doesn't attempt to breathe for you. It's intended for those who have trouble exhaling against the pressure.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.

I'll wager you have a VPAP Auto. (Will say VPAP Auto by the power button)
Which has 3 modes: CPAP, S mode and Auto.
CPAP is single fixed Pressure.
S mode is bilevel with two fixed pressures, IPAP and EPAP. S is for spontaneously triggered.
Auto has a Min EPAP, a Max IPAP, and a settable PS. It will adjust between the limits holding the PS=IPAP-EPAP fixed.

Mongo you are correct, this is a vpap auto. I found the clinician manual on this site and it was very helpful. Have not been able to decipher what spontaneous means though. Stool working on the jerky inhalation. Not sure at this point if that is the culptet for the mask leaks either. Didn't have these problems with the Phillips bipap.

An S mode (Spontaneous) bilevel machine changes between high and low pressure when it detects that you have changed between inhale and exhale. This is "normal" bilevel.

A T mode (Timed) bilevel machine switches between high and low pressure based on it's own timing, trying to force you to breathe on its schedule.

A S/T mode (Spontaneous/Timed) bilevel does spontaneous mode most of the time, but will go into high pressure mode if you fail to inhale within a certain time. It lets you breathe on your own schedule, but will take over if necessary.

Did you see a setting called "easy breath"?
When switched on, the Trise is grayed out; and the pressure rise fall curves are more "gentle."
Might be the solution to "jerky"
